LENS SHADES SELECTION FOR OXYGEN FUEL GAS APPLICATIONSMaterial Minimum Recommended*
Size Protective Shade Operation Inches Shade Number Number
Oxygen Fuel Gas Welding )(OFW) < 1/8 4 4-51/8 to 1/2 5 5-6
> 1/2 6 6-8
Oxygen Fuel Gas Brazing 3 3-5
Air Fuel Gas Soldering 2 2-4
Oxygen Fuel Gas Cutting (OFC) < 1 3 3-41 to 6 4 4-5
> 6 5 5-6
* As a rule of thumb, start with a shade that is too dark to see the weld or cutting zone. Then go to a lighter shade, which gives sufficient view of the weld or cutting zone without going below the minimum.
